Had an exhaust leak at the front pipe to exhaust manifold, had to change the front pipe gasket, dealer part price 52$, auto parts store 11$.
Gotr done, the O2 sensor is mounted to flange that bolts to the side of the front pipe, the O2 sensor blocked the drivers side stud. The flange was hitting the exhaust stud.
Managed to loosen the drivers side stud and removed the passenger side stud and spring from the front pipe, then removed the O2 sensor flange. Dropped the front pipe enough to remove and replace the front pipe to exhaust manifold gasket.
